Rock mechanics in the investigation and construction of Tumut 1 Underground Power Station, Snowy Mountains, Australia

T. 1 power station is located under the lower part of the very steep eastern wall of the Tumut
valley, about 1100 feet vertically below the surface, 1200 feet in from the river, and 150 feet
below the level of the river bed. The arrangement of the station is shown in Figure 4.
The largest chamber, the machine hall, is 306 feet in length, 77 feet in maximum width, and 104
feet in maximum height.

The power station is at an advanced state of construction and is scheduled to be in operation
early in 1959. The construction of T. 2 power station, which is of generally similar design to T. 1 and
located 5 miles downstream, was commenced in 1958.
